CIM20LAPP1C-10

CIMMYT's Latin America product pipeline Tropical Lowland (LatAm-PP1C) focuses on developing intermediate-maturing, yellow-grain, high-yielding maize hybrids that are drought tolerant, resistant to MLB and ear rots, and are suitable for feed use in tropical rainfed dry/wet low-altitude areas in Latin America.   General Information   Region Latin America   Adaptation/Agroecological zone 0 - 1200m above sea level   Type of product Three-way hybrid   Year first announced 2022         Grain Characteristics       Grain color Yellow Grain yield   Grain texture Semi-dent Grain yield under optimum conditions 7.6 t/ha       Grain yield under rainfed conditions 6.0 t/ha   Biotic Stress Performance Grain yield on-farm 6.7 t/ha   Maydis leaf blight (MLB) (1-9) 3.5 Grain yield under drought stress 4.1 t/ha   Tar Spot Complex (TSC) (1-9) 5.1       Diseases are scored on 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible Agronomic Characteristics   50% anthesis  56 DAP       Plant height 247 cm   Seed Production Characteristics Ear height 118 cm   Female seed yield  6.0 t/ha Ear position (ratio) 0.48   Male seed yield  3.3 t/ha Ears per plant 1.0   Nicking 0 days Ear aspect* 2.4       Bad husk cover 2.7%   Comments Ear rot  6.5%   Product information is based on data from the 2020 CIMMYT LatAm Stage 4 Regional Trials and 2021 Stage 5 Trials.
